Which code does this activity belong in?

Petroleum refineries perform the initial conversion of crude petroleum into refined petroleum through fractionation, straight distillation, or cracking. The boundary separates this primary refining activity from downstream manufacturing: asphalt paving and roofing products made from purchased asphaltic materials are classified in Asphalt Paving, Roofing, and Saturated Materials Manufacturing, while specialty petroleum products such as lubricating oils, greases, waxes, and brake fluids made from already-refined petroleum are classified in Other Petroleum and Coal Products Manufacturing.
